Filter Elements 2
2. Preface
Filter elements are the virtual part of a filter through which the filtration process is realised. For the different liquids and applications Filtration
Group developed different filter materials. Therefore a variety of elements are available which would fit into the same housing, but would suit
different applications.
3.1 Filter material PS and Sm-N
Depth filters consisting of several layers of glass fibre (progressive design) to filter hydraulic oils and lubricants, flame resistant liquids, fuels
and synthetic liquids.
PS is available in ratings of 5 µm (c), 7 µm (c), 10 µm (c), 15 µm (c) and 20 µm (c) according to ISO 16889 (3µm, 6 µm, 10 µm, 16 µm and
25 µm according to ISO 4572) with a very high dirt holding capacity and simultaneous very low flow resistance.
Sm-N 2 is available in ratings of 4 µm (c) according to ISO 16889 (2 µm according to ISO 4572) with an extremely high dirt holding capacityfor very demanding requirements in regards to the filtration quality, for off-line filtration and for single-pass applications.

In a hydraulic or lubrication system a filter has the task to reduce the contamination to the accepted cleanliness level and to keep it for as
long as possible. For the identification of solid particles in industrial hydraulics it is common practice to count particles according to ISO 4406.
Subsequently the achievable cleanliness classes of the Sm-x and Sm-N. These values mirror our longtime experience in designing hydraulic
filters and could be considered as guide values.

Deep filters with glasfibre filter material for all purposes. Filter performance, retention rates and the achievable cleaniness classes are fully
corresponding to the new PS filter material.

3.3 Filter material Mic
-
Depth filters made of cellulose or glass fibre layers with a high dirt holding capacity and a low flow resistance. Degree of filtration 10 µm and
25 µm according to FGC norm. Use in hydraulic oil and lubricants filtration as suction filter as well as low cost filtration in plants with minordemands in regards to the filtrat quality.

3.4 Filter material Drg
Surface filters made of stainless steel wire mesh with a very low flow resistance designed in the following weaves: plait, twill and linen. Degree
of filtration 10 µm, 25 µm, 40 µm, 60 µm, 100 µm, 200 µm, 300 µm and 500 µm. For a wire mesh filter element the degree of filtration isdetermined by the largest diameter of a globular particle which would be able to pass the fabric. Wire mesh filter elements are used in hydraulic
oil and lubricants filtration as suction or coarse filters, for high viscose fluids as well as safety filters for coolant filtration. Wire mesh elements
possess a defined removal size as surface filter and a low dirt holding capacity as depth filter.

3.5 Filter material KS-Mic
Depth filter consisting of several, coordinated, binder-free polyester materials with a very high dirt holding capacity and low flow resistance.
Degree of filtration: 25 µm according to FGC norm. Use as disposable filter in coolant filtration.

3.6 Filter materials WS-Mic, WS-Sm-x and WS-Sm-N
Filtration Group WS-elements for water removal are available as water absorber elements WS-Mic 25 with a low filter efficiency for particles or
in combination with the highly efficient Sm-N 2 and Sm-x 10 configuration. A super absorper will change its chemical structure while absorbing
water and indicates the amount of absorbed free water by an increase of flow resistance. The free water will be absorbed until the saturation
limit is reached. WS-elements are applicable for all common lubrication and hydraulic fluids. The filter property complies with the corresponding
Mic-, Sm-x- and Sm-N 2 element. The flow resistance of a water-free liquid would be insignificantly higher.
4. Quality assurance
